The nearest species to this plant is I think Liparis 

 tricallosa Echb. fil. of the Sulu Archipelago. It differs 

 in its laxer spike coloring of the flowers and orbicular lip 

 with the very different callus. The callus is rather 

 difficult to describe. It has the appearance of being 

 formed by two portions of nerves picked up into a short 

 elevated part, with a depression in front where the veins 

 had begun to bifurcate.
